What is the difference between a dangling pointer and memory leak?

Question

I'm new to C++ and would like to ask if the code below is an example of a dangling pointer or a memory leak because it is pointing outside the dynamically allocated array:

int * n = new int[10];
for (int prev = 0; prev < 10; prev++) {
    *n = *(n + prev + 1);
}
delete[] n;
n = nullptr;

What is the difference between a dangling pointer and memory leak?

You could say a dangling pointer is the opposite of a memory leak.

One is a pointer that doesn't point to valid memory, and one is valid memory that nothing points to.

(But as the other answers point out, your code is neither.)
